Events include a party in the Uncas Ballroom with tickets at $100 apiece, acrobats performing in Mohegan Sun Arena, and several more parties in the casino’s nightclubs, restaurants and in the shopping concourse.

“This is a really popular night,” Dale Wolbrink, Foxwoods public relations manager, said. “We roll out the red carpet.”

Foxwoods is featuring a Miami-themed celebration in the Miami Lounge & Cigar Bar, along with roving entertainment, cruise giveaways, a comedy show and parties in the casino’s nightclubs and its High Rollers bowling alley.

The two casinos are doing so much, in fact, that many smaller competitors are doing less than in past years.

“We’re going to run the normal hours, 10 to 10,” said Tim Chartier, manager of Engine 6 Pizza in Norwich, an eatery that also offers catering for parties. “I do expect to be here later to make sure everything runs smoothly.”

“New Year’s Eve for us is like a Friday or Saturday night,” said Rodney Green, owner of Olde Tymes in Norwich. Green said his restaurant will close at 9 p.m. as usual.

“We’re doing New Year’s specials and a toast” at midnight, said John Worney, general manager of Norwich pub Harp & Dragon. “I believe the casinos have stolen our thunder.”

Of course, not everyone will be partying tonight. About 18 percent of Americans — more than one in six — say they’re not celebrating on New Year’s Eve at all, according to the AP-Times Square poll.
